Be it known that l, MARTIN L. KEYES, a citizen of the United States of America, and a resident of Carthage, Jefferson county, New

York, have invented certain new and useful Improvements in Burial-Case Machines, of which the following is a specification.

My invention relates to a machine to be used in the manufacture of burial-cases where the Io cases are formed from wood or wood-pulp; and it consists in the mechanism hereinafter pointed out and claimed.

The object of my invention is to provide a machine for commercially manufacturing I5 burial-cases Afrom wood or wood-pulp by machinery, which I accomplish by the mechanisin hereinafter more fully described and claimed.

In the drawings, Figure 1 illustrates a perzo spective view of my rotating cutter or smoother and the finished product. Fig. 2 represents a plan view of the cutter and adjustable former. Fig. 3 is a cross-section on line A .B of Fig. 2. Fig. 4 represents a side of z5 the guide or flange on the former, broken linesY indicating parts removed, the section illustrating the means for adjusting the former.' Fig. 5 is a cross-section on line C D of Fig. 2. Fig. 6 is a plan View of driving-gear and 3o other parts ofthe machine. Fig. 7 is a section on line E F of Fig. 2. Fig. 8 is asection on line G H of Fig. 2. Fig. 9 illustrates the key for operating the adjustment. Fig. 10 is the adjusting-plate for adjusting the rotary cutter.

In the drawings similar reference characters refer to corresponding parts in the various views.

In manufacturing burial-cases from Wood- 4o pulp trouble is encountered in handling the cases as they come from the hydraulic press Where they are formed into shape. I do not, however, wish to limit myself to the use of this machine solely in the manufacture of burial-cases from wood-pulp, as it can lbe used on burial-cases manufactured from wood or other fibrous material.

In the drawings, l represents the inverted conical-shaped rotary cutter, driven by power. 5o Cutter 1 consists of a series of independent circular cutters forming cutter-blades 2 with cutting edges 3. The independent cutteru blades aremmounted on a driving-shafte`ach independent cutter being clamped or splined 3, to theshaft by well-known means, and in this instance they are shown in the form of an inverted cone for operating upon the incline surface of the burial-case.

-1 is the driving-shaft, on which and to which the rotary cutters are mounted and rigidly 6o held. The series of cutters having cutting edges are in the shape of an inverted cone in this instance, each cutter being spaced on the shaft by a washer and the cutting edge of 'each rotarycutter,includingthecutteritself, 65

is set on an angle to the line of theshaft, the incline being `shown at eta, Fig. 5, and the washer at the top is on an incline 4b, so that the rotation of each cutter will swing each `cutter the distance of the space between the 7o cutters. Partially surrounding the rotary cuttersis hood 5, into which thedustis` thro wn and it may be extracted or taken out by ordinary suction or air-blast. These parts are mounted on frame or table 6. An adjust- ,able former 7 is mounted on the frame or table and is provided with central opening 8, on theA inner surface of which I provideE continuous endless rack 9, which meshes with and is driven by spur-gear l0. Above the 8o lspur-gear 10 I provide guiding-collar llfgearf, 10 heilig splined to shaft 12, also carrying guiding-collar 11, loosely mounted on the shaft. Splined to the bottom of shaft 12 I lmount gear 13, which meshes into gear 14, mounted on shaft 15, supported in collar 16, surrounding shaft 12, power being applied to driving-pulley 17, which runs on shaft 15. Gear 14 is either a part of or mounted on hub 18, Which rotates on shaft 15. Sleeve 16 (illus- 9o trated in Figs. 3, 5, 6, and 7) is mounted loosely on shaft 12, so that the same may swing on the shaft as a fulcrum, and gear 13 issplined to shaft 12 for imparting power through the shaft to spur-gear 1Q, splined thereto for ro- 95 tating the same. The Vertical shaft 12 is horizontally movable toward and from the cutter-shaft to permit movement of the rotating former to and from the cutters. To this end the table is formed with au elon `loo gated slot or opening in the vertical` plane, including the shafts 12 and 4, through which vzo the shaft 12 passes and in which it is laterally movable. The shaft l2 is mounted in and usually carried by a sliding plate or journal-box h, (see Figs. 3, 5, and 7,) confined in and supported by guideways h on the under side of the table 6 to permit movement of the shaft 12 and its attached parts toward andl from the cutter-head. The pinion l() and the idler-retaining guide-roll 1l are yieldingly held to the former, and the former is thereby yieldingly held to the thrust or bearing band 28, with the case carried by the former yieldingly pressed to the cutters by suitable lnechanism.A For instance, I show horizontallyswinging lever 19 beneath the table 6 and at one end fulcrumed thereto at 19a and at its opposite end at 22, having a suitable weight 1QC attached thereto by cord 20, passing over pulley 2l. The lever is pivotally attached to the sliding box h, car-rying the shaft 1.2, by a link, so that the weight constantly tends to draw the lever toward the shaft 4 and through the medium of said link connection constantly tends to push the sliding box h in the same direction. By means of the handle end of the lever the box h and shaft 12 can be moved back from the shaft 4 and its part-s and `permit release of the former and the insertion or removal of a case.

It will be noticed that gear 13 can be swung with collar 16 through the operation of the mechanism already described and is held in position so as to bring the former and the work carried on the former into contact with the rotary cutter by means of the weight holding the parts in Contact.

By applying power to drive-pulley 17 spurgear 10 is rotated in contact with Arack 9 in opening 8 of the former, and by this operation when the burial-case 23 is placed in the inverted position on former 7, its inverted top resting on rabbeted surface 24 :on the outer side of former 25, the external surface' of the case is presentedto the rotary cutting action of the cutters, bringing its external surface in to,sm'ooth and. uniform shape. The

Y casa-when in position is best illustrated in' will cut completely the space between the The series of washers are designated by d and are placed between each saw, so'

that by the whipping action of the saws in their rotary mot-ion each saw travels the space between it and the adjacent saw through the operation of locating the saws on an incline to the center lineof the shaft. Other forms of 24 and acts as a guide for the former.

inside of opening 8 in the former against projecting surface 27 for the purpose of steadying the spur-gear and the movement of the former. The former 7, which is located on the table or frame, has the outer rabheted surface 24, forming a continuous track or projecting bearing-surface, which is held to and runs in contact with band 28 below. the rotary cutter. (Best illustrated in Fig. 5.) This runs on ball-bearings 28a, Fig. 5, the balls being interposed between the angle of 28 and support 28h, held to the frame by support 28C, Figs. 1, 5, and 10. The external surface of rotary band 28 runs in contact with the vertical face of the rabbeted surface The rotary cutter-shaft 4 is made adjustable at the bottom through the operation of adjustable plate or support 28, resting on the table6 and which can be swung and fastened through the operation of slots 28.1 in each end of plate 28C through the operation of bolts and nuts 28e. By this operation the cutting edges of the rotary cutter `can be made adjustable for regulating the depth of the cut made on the case. The block 28b rests on the plate 28, and the shaft 4 passes down through said parts and through the table 6, which is slotted to permit the adjustment of said shaft toward and from the former. Power is applied to the rotary cutter through the operationof pulley 29 on shaft 4 ffor impar-ting rotary motion to the cutters.

The burial-cases after they come from the hydraulic press are suitably dried in ovens before being operated on by this machine, and it is important to have adjusting mechanist'n in the form to accommodate different sizes oflburial-cases and to compensate for the shrinkage which may be in burial-cases of thesaxne size, it being important that former 7 should iit the opening in the casewhile it is being operated upon by the cutter. For accomplishing "this adjustment I construct a portion of the former in two parts 30 and 3l, Fig. 3, the two parts being arranged to engage and run in contact with each other on plain ysurfaces 32 and 33, Fig. 3, so that the parts may be independently moved in the direction of the length of the former, which is accomplished by screw 34, Fig. 8. The former `can thus be increased or diminished in external length without varying its width by the longitudinal sliding movement of the U- yshaped section 30 on the continuous body 3l of the former. The section 30 Iis seated in the exterior reduced Vor `rafbbeted portion 32 33401 the former, as before described, and the screw 34 passes inwardly through the end of the sliding section 30 and through a nut held therein and at its inner end is loosely'con- -fined to the end o'f 'the body of the former. The rotation of the screw in one direction reduces the exterior length of `the former by sliding section 30 inwardly on the main section 3l -or'body of the former, while opposite rotation of the screw increases the external IOO IIO

length of the former by forcing said sliding section outwardly, so that the former can be expanded within a burial-case located thereon to firmly clamp the case thereto. rIhe screw can be rotated by detachable key 34. The sliding section 30 is held down to its seat on the former-body by suitable means, such as plates secured to body 31 and projecting over section 30. The plate o is secured on the top edge of the former-body 3l and projects over the top face of the end of the sliding section 30 between the two plates 0 0, secured to said sliding section. The plates o o slide along the end edges of the plate o during the adjustment of the sliding section and form guides holding the same against lateral displacement. Plates c c are secured by screws d to t-hc side portions of the formerbody and project over the inner ends of t-he sliding section to hold the same down in piace. As the sliding section 30 carries a portion of the bearing face or track of the former, it is desirable to provide means to break joints at the junctions between the portions of said track carried by the former-body 3l and slidingsection 30, and thereby maintain the practically unbroken bearing surface or track 24, traveling against the roll or band 28, and hence avoid such lateral play or movement of the former during its rot-ation as would vary the depth of cut in the case by the cuttinghead. Plates R R, with their ends overlapping or breaking joints, are secured at R` to the tracks of the former-body 3l and sliding section 30 (see Fig. 4r) to accomplish said before-mentioned purpose and form guides for the roll 2S over the breaks in the track between the ends of the sliding section 30 and the body of the former.

Changes in details of construction will readily suggest themselves to one skilled in the artwithout departing from the spirit of my invention.
